3113 filaims.

This invention relates to means for automatically setting type in a typesetting machine, and more especially to the employment of a machine adapted to be driven by a typesetting machine or driven separately and using a control sheet which may be prepared by a reporter or other persons on a special typewriter such as is described in my copending patent application, Serial Number 426,854, and having thereon a plurality of code characters, each code character comprising a plurality of cell controls. This control sheet is adapted to be later transferred to the mechanism hereinafter described whereby the typesetting operation will be automatically performed without the necessity of the operation of the keyboard of the typesetting machine by an operator as the mechanism hereinafter described is adapted to be installed. instead of the manually operated keyboard as now occurs on a. typesetting machine.

Another object of my invention is to provide a special mechanism adapted to be associated with a typesetting machine and to operate therewith and to receive a control sheet having imperforate code characters thereon with each code character usually comprising a plurality of cell controls, and this control sheet can be transferred to any desired place whether distant or near, and by actual bodily transfer or by television, or by an electric typewriter operated by a circuit between distant points, and can then .be placed in the mechanism hereinafter described associated with a typesetting machine to automatically set the type therein.

Another object of my invention is to provide a mechanism ,adapted to be associated with a typesetting machine for automatically setting the type therein from a control sheet which control sheet may be written out by a reporter or typist on a typewriter having special type bars thereon in association with the legible character, a code character comprising a plurality of cell controls so that the typist can write out the report and at the same time write the code characters in association therewith, and this control sheet can then be transferred to the mechanism hereinafter described for automatically setting the type therein, although I desire it to be understood that if this control sheet is prepared in any other suitable manner wherein the legible characters are not necessary to be shown in connection with the code characters, the legible characters may be dispensed with as they perform no effect on the apparatus associated with the typesetting machine, but merely serve as a check to anyone proof-reading the control sheet to see that the proper characters appear on the control sheet.

Another object of my invention is to provide a mechanism adapted to be associated with a 5 typesetting machine and being adapted to re ceive a control sheet having code characters thereon for automatically operating the typesetting machine to set the type therein comprising light sensitive means adapted to successive- 1o ly scan the cell controls in each code character to automatically operate the typesetting machine to set the type therein.

Another object of this invention is to provide means adapted to be associated with and 15 may be driven by a typesetting machine whereby the type will be automatically set in the machine from a suitable control sheet.

Another object of this invention is to provide a machine which is adapted to be attached to 20 a typesetting machine and which may be driven thereby or may be driven independently and to be operated by a control sheet having cell control characters thereon with a photo-electric or light actuated cell mechanism for successively 25 scanning the cell control portions on the control sheet for automatically setting the type in the typesetting machine, and means are provided for automatic operation of this machine whereby when a complete line of code matter has been 30 scanned and the type set therefor, the mechanism will return to a new line position and the lines of code matter will be successively scanned to set up a combination of elements for each code character on the control sheet for selectively 35 operating the key rods for selectively setting the type in the typesetting machine.

I am aware that heretofore certain mechanisms have been employed using a perforated tape to cause the typesetting machine to be op- 40 erated therefrom, and also other attempts have been made at operating a printer or typesetting machine from an imperforate control sheet, but so far as I am aware, I believe that the use of an imperforate control sheet having a plurality 4 of cell controls for each character of the typesetting machine adapted to be successively scanned by a light sensitive cell for automatic operation of the typesetting machine is my invention, and it is an object of this invention to provide means to automatically set the type in a typesetting machine by the successive scanning of cell controls in a code character to automatically set a particular letter or character in a typesetting machine.

Referring more specifically to the drawings, it will be seen by observing Figure 1 that my automatic typesetting mechanism is adapted to be placed in the same position as the manually operated key board is normally placed in a conventional line casting machine.

In Figure 1 is shown the supports I0 and II of the typesetting machine frame, on which the base plate l2 of my mechanism is adapted to be mounted and secured in place by bolts i3 and I4,

and secured to this base plate at each end thereof are the end plates l5 and I 6 which are secured in position on the base plate l2 by any suitable means such as bolts i1 and I8 and I 9.

In order to clearly show how my mechanism is associated with a typesetting machine, I show the assembler drive pulley 26 with belt 2| thereon and in the rear of this mechanism is the intermediate drive shaft 22 which is mounted in frame 24 and has secured thereon pulley 23 on which belt 25 is mounted, said belt being also mounted on a pulley 26 which is secured on the main drive shaft 21 of my mechanism.

Also shown in Figure 1 is a portion 28 of the frame of the typesetting machine to which is secured support 29, which is adapted to support the lower end of the conventional key rods 30 in a conventional manner which normally is. that of having a portion cut out of the lower end portion so that a portion thereof will project below the support 29 and the shoulder thereon rest on this support 29. The conventional key rods are 3 adapted to be operated automatically by my bler has secured to the lower end thereof in a pivotal manner a link 36 which is connected to the assembler lifting mechanism which will be later described.

Also in Figure l is shown the line delivery carriage lever 35 which is fixedly mounted on shaft 36 which is conventional and is adapted to cooperate with the clutch mechanism which will be later described.

Main drive shaft 21 (see Fig. 6) has mounted thereon a cam 80, and along-side this cam is another cam M and further out on the main drive shaft is another cam 42, and further along the main drive shaft is another cam 43, and

. along-side this is another cam 44 which is in close proximity to the end plate l6, and on the outside of end plate l6, and near the end of the main drive shaft which projects outwardly from the exterior from the end plate I6 is anothercam 45. vThe main drive shaft is shown as being constantly driven as above described by the typesetting machine, though it may be driven from a separate source of power, and the cooperation of the various cams previously described in conjunction with the mechanism will be taken up separately in conjunction with the mechanism which is operated by each of the respective cams.

Fixedly mounted on main drive shaft 21 is a spur gear 46 which meshes with an idler spur gear 41 mounted on stud bolt 48, and this gear 67 meshes with a spur gear-'49 which has integral therewith a pinion 50 (see Fig. 2). This combined gear 49 and '50 is rotatably mounted on stud shaft 5|, and pinion 50 meshes with a spur gear 52 which is loosely mounted on an intermittent- 1y driven shaft 53. Gear 52 has a plurality of concentric holes 56 therein which are adapted to be engaged by a pin 55 in clutch arm 56 which is slidably mounted on intermittently driven shaft 53 by means of a key 51 which is fixedly mounted in shaft 53 andflts into opposed slots 58 in the hub portion of clutch arm 56. The hub portion of clutch arm 56 has a circular cavity 59 therein large enough to receive a compression spring 60, and a washer 6| is mounted between the compression spring 60 and the key 51 and 75 Fig. 48).

fits loosely in open end of cavity 59. Key 51 is secured in the shaft by means of a pin 62.

The shaft 53 has a collar 63 integral therewith which fits into a suitable enlarged circular cavity in the hub' portion of spur gear 52 (see Clutch arm 56 is normally held away from spur gear 52 so as to prevent the pin 55 from engaging one of the holes in the spur gear 52 by means of a lever 64 which has a sloping surface 65 on the end portion thereof, and the other end of this lever 64 is pivotally mounted intermediate its ends as at 66 in a projection 61 which projects from the end plate I5.

A set screw 68 is mounted in the lower end of lever 64 below the pivot point thereof to limit the outward swinging movement of said lever, and a compression spring 69 is mounted between member 64 and the end plate I5 to normally force said lever away from said end plate and into engagement with-the clutch arm 56. End plates I5 and I6 have upwardly projecting portions 10 and '1I nearthe front of the device (see Figs. 1 and 2) for supporting the carriage mechanism and the scanning" mechanism associated therewith. Secured on top of the projections 10 and H are bars 12 and 13, the bar 12 being secured by any suitable means such as cap screws 14 and 15. Bar 13 is likewise secured in position by any suitable means such as cap screws 16 and 11, and spacer blocks 18 and 19 are also penetrated by these cap screws, and on top of these spacer blocks is likewise secured by the said cap screws 16 and 11 a bar '80, said cap screws passing through bar 13 and spacer blocks 18 and 19 and the top bar 80, leaving a space 8| between the two.

bars.

Secured on bar are the vertically disposed support members 82. and 83 which are spaced apart from each other, and adjustably mounted on these members82 and 83 is a cross bar 84 which is'secured in position by any suitable means such as set screws and 86, and pivotally and adjustably mounted on member 84 is a lens bracket 81 which has a hub portion 88 penetrated posed support members 82 and 83 by any suitable means such as set screws 93, and intermediate the ends of this upper cross bar 92 is secured a bracket 94 which has a slot therein penetrated by a clamp bolt'96 having wing nut 96a thereon for adjusting the position of the bracket to regulate the position of a source of illumination such as an electric light bulb 91 which is mounted in a socket 98 which is secured in the bracket 94 and a shade and deflector 99 is secured over this source of illumination 91 for directing. the rays of light downward against lens ill, (see Fig. '1).

their proximate side portions the grooves or trackways I06 and I01 respectively, (see Figs. 1, 'I and 11). The carriage mechanism comprises a framework composed of members I08 and I09, joined together by a member I I0 which has a rack III on the lower surface thereof. The member I08 has wheels II2 rotatably mounted on each end thereof and member I09 likewise has wheels II2 thereon, all of said four wheels II2 running in the grooves I06 and I01. Projecting upwardly from the top surface of members I08 and I09 are lugs H4 and H5 in which is loosely mounted a rockershaft II6 which has secured on the outer ends thereof arms H1 and H8 which project upwardly and have secured thereto plate member II9 which has an elongated slot II3 therein through which pin I2I projects. Pin I22 projects through holes in one end of plate member' H9 and alsothrough a hole in pivoted lid member I53.

Pin I22 is loosely mounted in a lug I23 on arm I I8 and has a compression spring I 24 thereon, and this pin projects through a hole I25 in member I26, and is tightly secured in said hole I25. Pin I21 is loosely mounted in-a lug I21 on arm I 20 and has a compression spring I28 therearound. This pin passes through a hole I29 in member I30, and is tightly secured in said hole I 29 and projects upwardly through the top of arm I20, which arm is adjustably secured on rocker shaft H6. The pin I2I has a collar I3I fixedly secured thereon to limit the upward motion of the pin with relation to the upper end of arm I20. Likewise, pin I22 has a collar I32 thereon to limit its upward motion with relation to arm, I I8. Arm I20 projects into slot H3 and the upper surface thereof is flush with the upper surface of copy support plate II9.

Members,l25 and I30 which are fixedly secured on pins I2I and I22 project downwardly and have outward projections I33 and I34, (see Fig. 12) The projection I33 is adapted to be engaged by an arm I35 which is fixedly secured on an oscillating shaft I36, and a U-shaped member I31 is fixedly secured on shaft I36 and'this is adapted to engage projection I34 at the same time arm I35 engages projection I33 to force the pins I2 I and I22 downwardly out of the holes in the control sheet to release the controlsheet when it is desired to shift same to a new line position. Arm

I20 can be adjusted along shaft II6 to suit width of copy. Shaft I36 is loosely mounted in the end plate projections 10 and H and has an arm I38 secured thereon to which is pivotally secured a link I39 which in turn is pivotally secured to a cam lever I40 which is loosely secured on a control shaft I19 and has a slot I42 therein in which is mounted a roller I43 which roller, due to the action of gravity, is adapted to follow a cam I44 on intermittent drive shaft 53.

The plate H9 is secured to the free ends of arms H1 and 4T8 by means of suitable'screws such as I45, (see Figs. 1 and 11). From the rear edge of copy support plate II9, lugs I46 and I41 project, in which is fixedly secured ashaft I48, on which is fixedly secured an arm I49 which arm can be adjusted along said shaft by means of a set screw I50. The arm I49 has an enlarged portion I5I on the free end thereof with a cavity I52 in the lower surface thereof which is adapted to fit over pin I2I closely enough to allow the control sheet to pass between copy support plate and cover plate I53 when shifting to a new line position (see Figs. 1 and 11). Arm I 49 is shown in raised position in Figure 11 for clearness as its position is that shown in Figure 1.

Rotatably secured on shaft I68 (see Fig. 11) is a lid member I53 which has curled portions I56 and I55 integral therewith and passing around shaft I88 so -that lid member I53 may be raised upwardly when desired, and this lid member is spaced from copy support plate H9 both at the front and rear portions thereof and is limited in its approach to plate I I9 by means of set screws I56 and I57. This lid member I53 has a slot I20a therein coinciding with slot H3 in plate H9 and through these two slots the scanning operation is performed on a control sheet I58 which is shown in position in Figure 11, and shown also in Figure 67; This control sheet has equally spaced perforations I59 in the marginal portions thereof into which the pins I2I.and I22 are adapted to fit to insure the control sheet registering in such a manner that the line of code matter thereon will coincide with the path of the beam of light, passing from lens 9! through the slots and through a window I60 appearing in bracket I6I which bracket is secured on bar 72.

Arm II7 has pivotally secured thereto as at I 62, a link I63 which is pivotally and slidably mounted on shaft I 66 which shaft is fixedly secured in arm I65 secured on shaft I66 (see Fi 11). 2

Similarly mounted as link I63 on shaft I66 is a link I67 which is pivotally secured as at I68 to member '0. On the other end of shaft I68 from that to which is secured member I66, is a bell crank lever I69 which bell crank lever is fixedly secured to shaft I66 by any suitable means such as a set screw I70. Member I65 is also secured on this shaft by any suitable-means such -as a set screw I 7i. Bell crank lever I69 in the other end thereof, has a roller I72 which is adapted to follow the cam'00 on the main drive shaft 27 by action of tension spring I69a attached to pin I 69b so that by this means the carriage mechanism is given an oscillating movement which will be later described.

Shaft I66 hassecured thereon an arm I73 which has a roller I78 in the free end thereof which is adapted to follow a cam I75 on intermittently driven shaft 53, the purpose of this cam I75 and arm I78 and associated parts being to lock the carriage out of oscillating position to prevent cam 60 from moving arm I69 to oscillate the carriage mechanism while the carriage is being returned to a position to start the scanning of a new line.

Intermittently driven shaft 53 has cam I75 thereon (see Fig. 1,1) which is so arranged that cam I75 has a cavity I75a therein so that while shaft 53 is in such a position as to cause cavity I75a to coincide with roller I79 it permits a free rocking motion of the carriage mechanism through bell crank lever I69 operated by cam 90, but when the shaft is in any other position to cause the roller I79 to be against the larger por-'' tion of the cam I75, then it causes roller I72 to be moved out of the path of cam 66 on constantly driven shaft 27 and, therefore, no rocking motion can beimparted to the carriage mechanism.

The arm I73 has pivotally secured thereto as at I76 a link I77 (see Fig. 11) which link is loosely connected to an arm I78 on a shaft I79 which shaft extends all the way across the machine andhas its ends loosely mounted in end plates I5 and I6. The right hand of shaft I79 looking from the front of the machine, projectsto the outside of end plate I5 and has secured thereto a lever I80 which has a pawl I8I pivotally secured as at I82 to a handle I83 which has secured thereto a leaf spring I86 for pressing the same into engagement with one of notches I86, as the case may be in a rack I87 fixed on the outer surface of end plate I5 for holding the lever in one of the two positions.

When this lever I80 is moved to cause the pawl to engage notch I86 in rack I87 the link I 77 will allow roller I75 to engage cam I75. Also mounted on shaft I79 is an arm I88 which is adapted to engage a switch lever I89 of electric switch I90 which is mounted on the inner side wall of end plate I6 which is a conventional toggle switch and controls the circuit to the source of illumination 97. Also secured on shaft I79 by any suitable means such as pin I92, is an arm I9! and in the free end of this arm I9I is pivotally secured as at I9Ia, a link I93, the lower end of which link is pivotally secured as at I96 to an arm I95 which is fixedly secured on shaft I96.

Shaft I96 is loosely mounted in the end plates I5 and I6 and at its ends and on said shaft in close proximity to end plate I5 is secured a collar I97 to prevent endwise movement of the shaft.

, adapted to engage a notch I99 in the lower end of member 200 which is pivotally secured intermediate its ends as at 20I on end plate I6.

The lever I98 is adapted to engage the notch I 99 only when the carriage is being returned to a position for a new line or when the hand lever is in inoperative position to cause the scanning mechanism to start its scanning operation at a proper position to keep from splitting a code character in the reading operation.

To the upper end of pivoted member 200 is pivotally connected a link 202 as at 203, and the other end of this link is pivotally connected to a lever 208 as at 205, and the lower end of this lever is fixedly secured on a shaft 206 which is loosely mounted at its end portions in the inner surface of theend plates I5 and I6.

The upper end of lever 200 has a roller 207 therein (see Figs. 37 and 38) which is adapted to follow the cam 98 on the main drive shaft.

A pin 2I8 is secured in end plate I6, and to this is secured a tension spring 2i I, the other end .of this tension spring being secured as at 2I2 to the link 202 in order to normally force the memher 200 to the position shown in Figure 7, and also causes roller 207 to follow cam 69.

Shaft 286 has loosely mounted thereon an arm 2 I3 with a roller 2 I 8 in the free end thereof which operates on cam M on main drive shaft 27. Pivotally secured to arm 2I3 as at 2I5 is a link 2I6 which projects forwardly and is pivotally secured in the free end of arm ZII which arm is fixedly secured on shaft I96.

In the free end of arm M7 is a pin 220 to which one end of link 2 I6 is pivoted. Connected to arm 2I3 is a tension spring 22I which is mounted in a manner similar to spring 775a (see Fig. 7), the purpose of this being to normally press roller 2| 8 against its cam 5i.

Loosely secured on shaft I96 is an arm 230 which has a slot 23I therein which cam 232 is adapted to have movement so as to give a sharp action on this arm from said cam. Pivotally secured to one side of arm 230 as at 233 is a link 236 which projects forwardly and is connected in the free end of lever 235, which is fixed on shaft 806. The end of the link 238 which is connected to lever 235 is slotted as at 236 to allow relative movement between pin 229 on arm 235 and link 234 (see Figs. 1 and 7).

The lever 238 has the rearwardly and downwardly projecting portions 248 which has a set screw 242 therein which projects upwardly and acting rocking cam 248 (see Figs. 46-51 inclusive) which is pivotally mounted on bolt 249 which is fixedly secured in bar- I83 and this doubleacting cam has an upwardly projecting portion 258 and a downwardly projecting portion 25L Fixedlysecured to the bar 183 are the guide members 252 and 253 in which are slidably mounted the escapement pawls 254 and 255. The one next to the bar being designated by the reference character 255, and the one located away from the bar is designated by reference character 254.

Tension spring 254a and 255a hold their respective pawls against an escapement wheel 259.

The upper portion of cam 248 designated by 258, is adapted to have engagement with an upwardly projecting portion 256 on pawl 255 and the downwardly projecting portion 25l of the: cam is adapted to have engagement with a projection 251 on pawl 254. Member 254 has the upper end portion thereof projecting farther out than the lower portion with a shoulder parallel to its longitudinal center at the lower edge of this projecting portion and this shoulder is half way the Width of the member 254 so that when this member is pushed backward, it will allow the escapement wheel to move one half of a notch and rest against this projection, the face of which is indicated by referencecharacter 258. The member 255 has an outwardly and downwardly sloping surface and the lower edge thereof is in a plane parallel to the lower edge of the member 254 and this is adapted to have engagement in one of the teeth on the escapement wheel and when this member 255 is slid backwardly it will allow the escapement wheel 259 toslip one half of a tooth and this tooth will rest against the shoulder 258 on member 254 and then when member 255 is pushed forward again the lower portion 251 of the cam 248 retracts member 254 and will allow the escapement wheel 259 to move another half notch and engage the lower surface 268 of member 255.

The escapement wheel 259 is rotatably mounted on a shaft 262 which is mounted in bearings 263 and 264 (see Figs. 1 and 7) on the lower side of bars 182 and I83, and on central portion of this shaft is secured a pinion 265 which is adapted to have engagement with the rack I II in bar H8 for controlling the movement of the carriage mechanism. Member I88 has secured thereto a flexible member 266'which passes over a pulley 261 secured to the inner sidewall of member I 6. This member 266 leads to the take-up mechanism which comprises a shaft 268 (see Figs. 1, 6, 42

Also fixedly secured on shaft 284 are arms 288 and 289 and on the free end of arms 282, 288 and 289 is fixedly secured a bar 298 on which are mounted friction members such as wide rubber bands 291 for gripping the paper for moving it to a new line position.

Loosely secured on shaft 284 are arms 292and 293 which have secured on the free ends thereof a bar 294 which is adapted to have sliding movement on bar 13 and to be supported thereby. The control sheet passes between bars 298 and 294 and beneath shaft 284.

A pin 295 is securedin link 284 and has the lower end of a tension spring 296 secured thereto,

is adapted to follow card 388 which has a cavity I 3880, therein where the roller 299 is adapted to rest when the mechanism has been moved to its extreme limit in pulling the control sheet to a new line position which is the position shown in Figure 14. Fixedly secured to the lower side of bar 88 is a bracket 38! which has an out-turned portion .382 in. the free end thereof in which is mounted a set screw 383 which is adapted to press against link 28! 'when the paper has been pulled to a new line position .to limit the pull imparted to the paper as shown in Figure 14.

On the most distant end of shaft 218 as shown in Figure 14 I have already described the arm 286. This arm 286 has a pin 384 secured therein to which is secured one end of a tension spring 385 and the other end of this spring is secured to a pin'386 which ismounted in the inner surface of end plate l6, (see Fig. '7), the purpose of this spring being to cause roller 299 to follow cam 388;

With the parts in the position shown in Figure 14 roller 216 is beginning to rise to a higher surface on a cam 215 and when this happens, thiscauses arm 219 to move downward with its link 28l and also it raises thebar 298 and releases gripper -29I from the paper and. at the same time roller 299 is beginning to rise on cam 388 which moves arms 285 and 286' to return the gripping mechanism to a position where it can grip the paper and bring the control sheet to a new line position at the proper time.
